ELEVATOR EVACUATION SYSTEM
FIELD OF THE INVENTION
The invention relates to evacuating people with an elevator system. Especially, the invention re- lates to a method, computer program and apparatus for evacuating people with an elevator system.
BACKGROUND OF THE INVENTION
Evacuation in buildings is usually a compli- cated issue to solve. Normally, in an evacuation situ¬ ation, the use of elevators may be prohibited, for ex¬ ample, due to legislation or that the elevators are not fire proof. When considering evacuation in high buildings, the question whether to use elevators has to be evaluated again. If a building is very high and a fire occurs in the middle in terms of height of the building, it might not even be possible to evacuate people from the upper half of the building using staircases, for example, due to a fire. Thus, the use of elevators might be the only option for evacuation. Due to this, elevators may be designed to be usable also in evacuation situations. For example, a lobby area may be smoke protected, the elevators themselves may be fire protected, separate power supply for emer- gency situations may be provided, shafts may be pres¬ surized etc.
A real evacuation situation, for example due to a fire, is a complex situation especially in high buildings where elevators can be used in the evacua- tion. People are afraid and their behavior might not always be rational under evacuation.
Furthermore, if both elevators and staircases can be used in an evacuation situation, it may be dif- ficult for the people under evacuation to decide which option (elevator/staircase) to use, i.e. which option would result in a quicker or more efficient evacuation procedure. Furthermore, the evacuation situation may involve also a special group of people, for example, handicapped people, to whom the only available evacua¬ tion method is an elevator evacuation.
Based on the above, there is a need for a so¬ lution which provides a more efficient evacuation pro- cedure when elevators are used in the evacuation.

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Figure 1 illustrates a method according to one embodiment of the invention. In step 100 it is identified that an evacuation mode is active in an el¬ evator system of a building. In this embodiment, elevators can be used in evacuation people from the building in an evacuation situation, e.g. in case of fire. In step 102 the amount of people in each build¬ ing floor to be evacuated by a normal evacuation ser¬ vice of the elevator system is determined. The deter¬ mination can be made using an appropriate technique or a combination of techniques. If the elevator system is a destination control system, the elevator system is aware of the floors to which people travel. Access control information may also be used in determining the amount of people in each building floor since the people arriving at a floor may have to use some iden- tification method in order to access the floor.
In step 104 it is determined whether there exists at least one person to be evacuated who is en¬ titled to a prioritized evacuation service. A person who is entitled to the prioritized evacuation service is, for example, a handicapped person who needs to use a wheelchair.
In step 106 an estimated evacuation waiting time for each floor to be evacuated by the normal evacuation service is calculated. The calculation takes into account that the at least one person al¬ lowed to the prioritized evacuation service is evacu¬ ated first and only then normal evacuation is performed .
In step 108 the estimated evacuation waiting time is caused to be displayed in each building floor to be evacuated by the normal evacuation service. This provides additional information to the people who are waiting in a lobby for an elevator that will evacuate them. Furthermore, since the estimated evacuation waiting time is known, each person is able to make an own decision whether to use stairs to evacuate or to wait for the elevator.
Figure 2 is a block diagram illustrating an evacuation procedure according to one embodiment of the invention. The embodiment in Figure 2 uses a floor-by-floor evacuation procedure. In other embodiment, the evacuation procedure may be a staged evacua¬ tion or fractional evacuation.
Block 200 indicates that an automatic floor- by-floor evacuation mode has been activated. The acti¬ vation results, for example, in a fire alarm or any other signal received by the elevator system indicat¬ ing evacuation situation. In block 204 it is deter- mined whether landing calls exist. If they exist, it means that there are people to be evacuated. In block 206 the number of cars needed per floor in defined. Block 202 indicates that occupant count is updated. The updating may be continuous or may be made after certain events. Thus, in block 206 it is possible to define the number of cars needed to evacuate the amount of people waiting in each floor. Cars are then dispatched to occupied floors, as indicated in block 208. The cars are loaded at the occupied floor, block 210. The number of occupants remaining at the floor may be determined by decreasing the floor occupant count by the car loads, block 212. If it is determined in block 214 that the cars are not loaded below a de- fined limit, the cars are expressed to the area of safety, i.e. to a predetermined rescue level, block 216. If it is determined in block 214 that the cars are loaded below a defined limit, the processing con¬ tinues to block 204 where it is determined whether landing calls exist. For example, the elevator car may be sent to the next floor to be evacuated to receive additional occupants. If landing calls remain to exist as indicated in box 204, the process described above is executed gain. If no landing calls exist, it is checked in block 218 whether the evacuation time has lapsed. If the evacuation time has not yet lapsed, the process returns to block 206. If the evacuation time has lapsed, the automatic evacuation mode ends, as in¬ dicated in block 220.
The occupant count in block 202 may be updat¬ ed based on several signals. The occupant count may be based on forecasts, various measurements (for example, using detectors, elevator weighing devices etc.), information from destination control panels etc.
Figure 3 illustrates calculating an evacua¬ tion time according to one embodiment of the inven¬ tion. Figure 3 illustrates a building which has N floors and where L elevators are used in evacuating people from the floors. In this embodiment, people are evacuated using floor-by-floor evacuation starting from the furthest floor to the rescue level. An evacu¬ ation time Tk per floor is calculated considering round trips 300 from floor N before reaching the floor k and the number of evacuation elevators L. Reference number 302 refers to people waiting for elevator evacuation in various floors.
The round trip time of an elevator and a waiting time per floor k may be calculated as follows:
TRT = 2Hs / v + 2ts + 2Mtm
N J,
Tk =∑∑TRT . . I L
i=k+l j=l
TRT = Round trip time of an elevator
Tk = Waiting time per floor k
H = Rescue level/floor
M = Car capacity (M persons)
s = Floor height
v = Speed on an elevator
ts = Stop time
tm = Passenger transfer time
Ji = Number of round trips per floor i carry¬ ing all waiting people
L = Number of elevators Prioritized evacuation service may be taken into account in the above formulas. For example, if a handicapped person is to be evacuated, it affects sev¬ eral parameters above. Normally the car capacity is M persons, but in the case of a handicapped person, the car used car capacity may be regarded as 1. The stop time tm is normally, for example, 10 seconds, and in the case on a handicapped person it is longer, for ex- ample, 20 seconds. The passenger transfer time is 1 second for normal people, but 10 second for a handi¬ capped person.
When determining the waiting times, priori- tized evacuation service may be executed first thus resulting in a faster evacuation for handicapped persons. When determining the waiting times for normal evacuation service, i.e. for people not entitled to the prioritized evacuation service, the time spent for evacuating the handicapped persons is taken into ac¬ count in the calculations. When the people to be evac¬ uated know the estimated waiting time, each person is able to make an own decision whether to use stairs to evacuate or to wait for the elevator. This makes the evacuation process more efficient.
The estimated evacuation waiting time calcu¬ lations may be executed several time or even continu¬ ously during the evacuation mode. For example, originally it was counted that in a certain floor there are 55 persons to be evacuated and the estimated evacua¬ tion waiting time was calculated based on this count. Some time later 25 persons chose to use the stairs and thus are no longer waiting for elevator evacuation. The elevator control system learns the updated people count waiting for the elevator evacuation (for example, via input means in a lobby or some other infor¬ mation source) . The elevator control system then makes new estimated evacuation waiting time calculations based on the updated count and provides an updated es- timation.
In one embodiment, two separate waiting times per floor may be calculated: (1) waiting time for pri¬ oritized evacuation service and (2) waiting time for normal evacuation service. These times may be sepa¬ rately displayed on each evacuated floor.
Figure 4 discloses a block diagram illustrat¬ ing an apparatus 400 according to one embodiment of the invention. The apparatus comprise a processor 402 connected to a memory 404. The apparatus may also com¬ prise several processors or memories. The memory 404 or memories comprises at least one computer program which, when executed by the processor 402 or proces- sors, causes the apparatus to perform the programmed functionality. The apparatus may also comprise a com¬ munication interface 406 configured to re¬ ceive/transmit information from/to external entities. The communication device may be used to transmit in- formation to be displayed on a display device on each floor during evacuation situation. The apparatus 400 is any processing device that is able to implement the features of the invention, for example, a server computer .
Figure 5 illustrates a system according to one embodiment of the invention. The system in Figure 5 is a simplified illustration of an elevator system where evacuation is performed when an evacuation mode is active. The system comprises an elevator control device 500 which is responsible for controlling eleva¬ tor cars 504A-504C. The elevator control device 500 is also connected to display devices 502A-502E provided on building floors. The elevator control device 500 is configured to calculate an estimated evacuation wait- ing time for each floor to be evacuated by a normal evacuation service, wherein the calculation takes into account that the at least one person allowed to prior¬ itized evacuation service is evacuated first. The ele¬ vator control device 500 then transmits the estimated waiting times to the display device 502E. Each display device 502A-502E thus displays the estimated waiting time relating to the floor where the display device resides .
In one modified embodiment of Figure 5, at least one elevator in the elevator system is a double- deck elevator. Thus, evacuation by the normal evacua¬ tion service may be arranged with a first elevator car of the double-deck elevator, and simultaneously, evac- uation by the prioritized evacuation service may be arranged with a second elevator car of the double-deck elevator .
The exemplary embodiments of the invention can be included within any suitable device, for exam- pie, including any suitable servers, workstations, PCs, laptop computers, capable of performing the pro¬ cesses of the exemplary embodiments, and which can communicate via one or more interface mechanisms.
